Black leather briefcase with initials PK

I lost my black leather Samsonite briefcase yesterday around 3pm near the Ogden Union Station, tucked behind the bus stop on 25th Street. It's a 14-inch case with a brass zipper, a slightly worn handle, and a coffee ring on the front cover. Inside there's a yellow sticky note with my initials 'P.K.' and a USB-C thumb drive, plus a small leather tag on the zipper pull that reads 'PK'. There’s also a thin red cross-stitch along the bottom edge that should help identify it, and I really need to get it back because it holds sentimental value.
